the unethical thing about these "permissions" is that some apps won't even run or load if you deny them access.
And it seems like every company now insist (demands) on having names, email addresses and phone numbers before you can use the products.

no need for such in the real world in most cases.
no real need on the internet either.

The thing about Gmail is they scan and in a sense "read" your emails and always have. And they use the information they gleam too. I've got an Gmail address and I use it for online stuff only. I don't use it for anything private, for that I use a private email address. It's not free but it is private and secure.
